please do question 2

please do parts 1&2 from part 2 diffusion across the membrane

Facilitated diffusion of glycerol into a cell is depicted below. Facilitated diffusion is the assisted transport of molecules across a membrane from a example glycertration to a lower concentration, using a transport protein. In this 2. Use the information in the image above: a. Which functional groups on glycerol tell you if it is a hydrophobic or hydrophilic compound? b. Why is glycerol moving from outside the cell to inside the cell in this example? c. What is meant by "carrier-mediated"? d. What is meant by "specific"? In Discussion Activity to do with your TA Active transport is the movement of ions or molecules against a concentration gradient. This movement requires energy and the assistance of a membrane protein. In some cases, ATP is directly hydrolyzed to form ADP and Pi to pump compounds against their concentration gradient. Given that the interior of the cell is a very crowded place, hypothesize as to which form of transport may be more useful to the cell ACTIVE or FACILITATED. Explain. Due to the structure of the membrane, some molecules will be able to pass freely through and some will not. This is the semi-permeables nature of the cell membrane. 1. Using me ngure below: a. Visually compare and contrast the compounds in the water below. What differences do you see between the two compounds in the water? b. Label the hydrophilic and hydrophobic compounds. c. Draw in the hydrogen bonds that are possible between a few of the water molecules in both images. d. Draw in the hydrogen bonds possible between the polar head groups of the lipids and the water. e. Draw in the hydrogen bonds possible between the hydrophilic compound and the water. 2. Based on the bonding you drew in above, which compound do you think will be able to pass through the membrane? Explain
